4 Claims. 1

The invention relates to railway vehicles and hicles, such as electriclocomotives.

In one type of electric locomotive used here-V tofore, the draft gear isremoved downwardly from the draft gearpocket in the vehicle bed. Thebrake rigging and other equipment just below the draft gear pocket mustbe removed before dropping the draft gear, which may require shopfacilities not usually found in the ordinary running shed or inspectionpit. Also, the draft gear pockets at the ends of the bed are connectedby a center sill to carry buffing and pulling forces from one end of thebed to the other. Separate sand boxes may be attached to any convenientpart of the bed.

One object of the present invention is to remove the coupler and draftgear from the draft gear pocket longitudinally of the bed and Withoutremovingthe brake gear and other equipment. I

Another object is to construct the draft gear housing with an integralbottom web to prevent the side walls from spreading laterally of thetruck bed.

Another object is to transmit the buffing and pulling forces from oneend sill to the other through the bed side members, instead of through acenter sill.

Another object is to form sand boxes integral with the truck bed at thejuncture of the side members and the end sills, thereby forming the sandboxes as part of the bufling and main carrying members.

Another object is to construct the sand boxes to obtain maximum strengthwithout affecting their functional characteristics.

Another object is to provide a lighter, more compact driving truck bed.

Other objects will be apparent to those skille in the art from thefollowing description and accompanyin drawings, in which:

Figure l is a top view of a railway vehicle driving truck constructedaccording to the invention and with portions of the truck bedcut away toshow the construction more clearly.

Figure 2 is a side view of the truck showing one of the motor mountingin vertical longitudinal section.

Figure 3 is a horizontal section through the couplin structure and draftgear pocket taken approximately on the line 3-3 of Figure 2 and drawn toenlarged scale.

Figure 4 is a vertical longitudinal section through the couplingstructure and draft gear pocket taken approximately on the line 4-4 ofFigure 1 and drawn to enlargedscale.

Figures 5 and 6 are vertical sections through a sand box at the lefthand end of the truck in Figure 1 taken approximately at right angles toone another on the lines 5-5 and 6-6, respectively, and drawn toenlarged scale.

Figures 7 and 8 are vertical sections through a sand box at the rightend of the truck in Figure 1 taken approximately at right angles to oneanother on the lines 'l'l and 88, respectively, and drawn to enlargedscale.

The truck includes wheel and axle assemblies l and journal boxes 2. Atruck bed has end sills 3 and side members 4 connecting the end sillsand provided with depending pedestal legs 5 for receiving journal boxes2 between them. Electric motors E are secured to the axle housings anddrive wheel and axle assemblies I. A bolster 6 extends laterally of thetruck between the side members and has a center plate 1 for mounting acar body center plate (not shown). Sand boxes 8, 9. [0, II at thecorners of the truck bed are cast integral therewith at the junctures ofv the side members and end sills and form the sole tial portion of sandboxes 8, 9 extend into end sill 3 and the box end Walls [6, [1 formreinforcing ribs for the associated sill 3 and side members 4,respectively. A sand filler pipe l8 extends upwardly and outwardly ofthe bed from top and outer side walls [2, l4 and an outlet l9. in bottomwall I3, provides for discharging sand to the rail.

Sand boxes I0, ll, at the right hand end of the truck bed (Figures 1, 2,'7, 8) extend diagonally between the associated end sill 3 and sidemembers 4. Each sand box [0 and I l forms a hollow receptacle havin atop wall 20, an inclined bottom wall 2|, an outer side wall 22, an innerside Wall 23, and end walls 24, 25. Top wall 20, bottom wall 2| and sidewalls 22, 23 form the bounding walls of the corresponding truck bedportion and end walls 24, 25 form reinforcing ribs for the truck bedportion. A sand filler pipe 26 extends upwardly and outwardly of the 3truck frame from top wall 20 and outer side wall 22. An outlet 21 inbottom wall 2| is provided for discharging sand to the rail.

Sand boxes 8, 9, H], H form part of the bufiing and main carryingmembers. This saves weight and at the same time accommodate the sandboxes without, in any way, reducing the load carryin sections.

Sill 3 at the right hand end of the trucklFigures 1 and 2) has anarticulated connection 28 to an adjacent truck (not shown) A draft gearpocket 29 is formed in end sill 3 at the left hand end of the bed'asa-structural part thereof and includes integral webs forming the top 45,bottom 46, and side-walls.41, 48-of the pocket. Draft gear pocket 29extends :longitudinally of the truck and opensforwardly of end sill 3,at 30, and projects inwardl'y'of transverse, vertical wall 3| of the endsill, substantially abreast of the adjacentpedestal leg 5 and beyondbrake hanger brackets '51.

' A draft gearl32 is received in,pocket'29 and is held therein byfollower stops 33Lsecured to the side .walls of the draftgear pocket byretainer bolts34. A coupler '35has a head .38 extending forwardly of endsill 3 and has a shank 38 extending intopocket 29 andsecured by a key 31to the draft gear. A filler block39 is bolted to end sill 3 in pocket'29adjacent opening 3-8, and a wear element '49 is dowelled to filler block39 andsupports the outer end of coupler 35.

Coupler '35 and draft-gear 32 may be readily removed from draft gearpocket 29 through opening 38% follows:

'Keyf3l is removed and coupler 35 is withdrawn through opening 30 frompocket 29. Element 40 is'lifted from filler block 39 and filler block 39is-unbolted from-end sill 3 and both are removed through opening 30. Afixture (not shown) of any suitable kind; is attached to the outer endof the draftgear to compress it vsufliciently to relieve the pressure onfollower stops 33. Retainer bolts- 34 then are-removed'and followerstops 33 are withdrawn through opening 30. pression of the draft geariseased by: releasing The a comthe fixture and the fixture and draft geararere- -moved through opening 30.

With this arrangement, :it is unnecessary to remove a brake beam 4|directly below draft gear :pocket --2 9 and associated brake-gear 42 43,"44 as would be'necessary if thecoupler and draft gear were removedfrom-the draft gear pocket downwardly-from the truck bed.

Furthermore, the draft gear pocket may be provided with a-housingthat-completelysurrounds the draft geanand integral bottom web 46 makespossible a lighter structure for the same strength as comparedto-the-structures used heretofore where the bottom of the'draft-gearpocket wasopen or was provided'with a removable wall-so that thedraft'gear and coupler could be dropped through the'bottom'opening.Ifdesired, the shaft for brake lever 49 may-beyjournaled in bearings 50integral with and depending from bottom'web 46 and side webs '41, 48.

-allemb0diments of the *invention but the structuremay'ibeimodifiedsubstantially without departing from the spirit of theinvention, and the exclusive use of such modifications as come withinthe .scopeof the claims is contemplated.
